Annrnoven BED-BOTTOM.

Tdi/ige Sslgrm'le nimh tu iu tlgse irtlcrs ntmt :mh uniting part nf tlge snm.

Be it known that I, WILLIAM B. INGERSOLL, of the city of New York, and State of New York, have invented a new and improved BefLBottom; and I do hereby declare that the following is a full and exact description thereof. And furthermore, I desire that Letters Patent of the United States may be granted to me: and my legal representatives for the same. i V

a a are oross-bars. To these bars is attachedl a number of pulleys arouudn'hich a small rope or cord is passe'l. r is .the rope; c are the pulleys; h h are arms to which the `cross-bar at the head of the bed is attached, one arm` at each end of the cross-bar, the other ends of the arms being attached to the side of the bedstead in such a manner as to allow. the eross-barto move up and down. ff are springs placed under each arm, or may be placed under the cross-barfand may be made of steel, India. rubber, or any other lsuitable material, and of any desired form. g is a windlass ,to which one end ot"l lche rope-is fastened. At one end of the windlass is a. ratchet-wheel and click for the. purpose'oftightening the cord. By this Varrangement the di'erent parts can easily be put together, and vin a few moments made to fit any common beflstead. Figure 3 is also a different arrangement, which may he applied to the side of the 'bedstead 'or fastened to one of the cross-bars. pp are pulleys or rollers. 0 is a ratchet-wheel attached to one pulley, which is corrugated. One end of the rope is passed between the pulleys, and as the pulleywith the ratchet is turned the rope is drawn through but cannot slip back, as the click and ratchet preventV the pulleys from turning,Y and in this way the cord is -drawn tight. Having the cross-bar at the head of the bed'to move up and down, a true inclined plane is secured, giving to the head of the bed one inch or six inches more or less elevation above the level, just as much-or as little as is desired. Also, by this' arrangement the cord is made tighter as the weight ofthe body presses down on it. A bed-bottom so arranged will not sag in the middle. -For a full-sized hed fifteen or sixteen pulleys are required, and should be aboutlthree inches lin'diameter, and the spaces between them the same; a little more or less will answer. The pu'lleys may be made of wood or metal. l

What I claim as my invention, and desire to secure by Letters Pat-ent, is-

'lhe combination of the pulleys c, around which the oord r passes, th/e cross-bars d, to which' the pulleys are attached, the movable arms h, the windlass g, and the springsf under the arms or head-piece or cross-bar, all as and for the purpose specified. 4
